The document outlines a sustainability agenda for a community and homes. For the community, it discusses establishing shared gardens, implementing a car share program, and upgrading the clubhouse with sustainable technologies. For homes, it explores options for solar power systems, solar hot water, and home energy assessments/upgrades. It provides cost estimates and concepts for each initiative to gauge community interest through a survey. The ultimate goal is to design the community and homes to be more sustainable.
